The Nightcrawler, also known as the Fresno Alien, is a cryptid that has made two appearances so far, one in Fresno, California and the other in Yosemite National Park. In both sightings, it's only seen in video footage. It appears to be a relatively short creature (approx. 4 feet in height).However a man in Poland has said to have seen the creature, confirming that this it could be a Nightcrawler. It is an extremely thin, white humanoid with no discernible arms. It also appears to be wearing a white gown or cloak of some sort.

According to certain Native Americans in the surrounding area, the Nightcrawlers have existed on Earth for a considerable amount of time and come from a planet consisting majorly of swampland. Their long legs are thought to help them maneuver through the boggy terrain. To these Native Americans, the swamp-world aliens are here on Earth to assist in an "awakening", to rebuild the connection between man and nature and subsequently bring peace and harmony to the planet.
